There is a difference between both solutions, the htohl() version
tracked the need for swap as a struct subscription member (which was
used when sending back events). Neils patch doesn't do that tracking.
I don't really know the implications of this, but maybe it would be
a wise idea to stay in the safe side and revert both patches for now.
